THE BASIC PRINCIPLES OF ER:YB:YAB CRYSTAL

The nonradiative transition costs Keep to the system WNR = W (0) exp(-alphap), where by p is the number of phonons matching the Power gap. The nonradiative transition prices of Er3+ exhibit temperature dependence per the multiphonon leisure concept. In Tm3+ the temperature dependence of nonradiative rest charges is sophisticated via the existence o
